Background
In daily life, a portable (or disposable) miniature atomizing heater is needed, and is used for certain functional products such as an atomizing and inhaling type drug delivery device for treating upper respiratory diseases, an electronic cigarette, portable electric mosquito coils and the like. However, at present, most of the conventional portable atomizing heaters adopt an electric heating tube (containing a resistance wire) for heating and atomizing, and because the resistance wire has small internal resistance, the disposable atomizing device must be equipped with a secondary battery with high capacity and low internal resistance, so that not only is the cost performance low, but also the secondary battery is easy to generate high temperature and even explode, and thus the industrial production and application of the atomizer are limited. The invention aims to solve the problems of heating and atomizing by adopting a resistance wire in the conventional micro atomizing heater, and provides the micro atomizing heater which utilizes heat energy generated by over-rated power of an electronic component.
The invention designs a micro atomizing heater using heat energy generated by over-rated power of electronic components, which comprises a shell, a mist outlet and a liquid storage body, wherein a heating body is arranged in the shell, and the micro atomizing heater is characterized in that: the surface of the heating element is tightly attached to the liquid storage film; the liquid storage films at the two ends of the heating body are tightly matched with the liquid storage body, so that the functional liquid stored in the liquid storage body is uniformly distributed on the heating surface along with the liquid storage films; the heating body is connected with the battery through an electrode; once the power is on, the heating body atomizes the liquid on the surface of the heating body by utilizing the heat emitted by the heating body which is several times of the rated power of the heating body, and the atomized liquid is discharged from the mist outlet to run. The method is characterized in that: the heating element is an electronic component, a resistor or other semiconductor devices. The heat receiver is a liquid storage film which is uniformly and tightly covered on the surface of the heating element, and the liquid storage film can be high-temperature and flame-retardant non-woven fabric or absorbent cotton or other substances capable of keeping liquid. The method is characterized in that: the heating body works in a critical state before being burnt out due to the excess rated power. The shape and size of the shell; the liquid storage mode and the volume of the liquid storage body can be selected at will according to the functional requirements.
A heating element (electronic component) in the shell is connected with the battery through an electrode; the surface of the heating element is covered with a liquid storage film (liquid adsorption material), and the liquid storage film is connected with the liquid storage body to ensure that the liquid to be atomized is continuously supplied;
after the power is switched on, the heating body works under the state of exceeding the rated power, so that high temperature is generated and the liquid covering the surface of the heating body is atomized. The lost liquid is continuously replenished from the liquid storage body in a siphon mode, and meanwhile, the heating body is prevented from being burnt. The invention has the advantages that the internal resistance of the heating element can be selected at will according to the requirements of the power supply, so that the alkaline zinc-manganese battery or other green disposable batteries can be utilized for power supply; the resistance is cheap, the specification is complete, the quality is guaranteed, and the atomizing amount of the resistance heater is higher than that of the resistance wire heater, so that the application space is relatively wider.
Detailed Description
Including casing 2, cap 1, play fog mouth 7, stock solution body 5, heat-generating body 3, stock solution membrane 4, 6 its characterized in that of electrode in the picture: the surface of the heating element 3 is tightly attached to the liquid storage film 4; the liquid storage film is tightly matched with the liquid storage body 5; the heating element 3 and the liquid storage film are fastened on the shell 2 by the shell 2 and the shell cover 1; the lead of the heating element 3 is led out by the electrode 6.
Including casing, play fog mouth, stock solution body, install the heat-generating body in the casing, its characterized in that: the surface of the heating element is tightly attached to the liquid storage film; the liquid storage films at the two ends of the heating body are tightly matched with the liquid storage body, so that the functional liquid stored in the liquid storage body is uniformly distributed on the heating surface along with the liquid storage films; the heating body is connected with the battery through the electrode; once electrified, the heating body atomizes the liquid on the surface of the heating body by utilizing the heat dissipated by the heating body under the condition that the power exceeds the rated power of the heating body by multiple times, and the atomized liquid is discharged out of the mist outlet for operation. The method is characterized in that: the heating element is an electronic component, a resistor or other semiconductor devices. The heat receiver is a liquid storage film which is uniformly and tightly covered on the surface of the heating element, and the liquid storage film can be high-temperature and flame-retardant non-woven fabric or absorbent cotton or other substances capable of keeping liquid. The method is characterized in that: the heating body works in a critical state before being burnt out due to the excess rated power. The shape and size of the shell; the liquid storage mode and the volume of the liquid storage body can be selected at will according to the functional requirements.
In a normal state: the surface of the heating body 3 is always covered by a layer of liquid film under the action of the liquid storage film;
power supply: can select any power supply (including AC, DC, pulse; primary battery, secondary battery, USB socket)
Etc.), conditions: the electric power required by the atomization generated by the heating element is met.
Electrifying the electrodes: because the selected voltage and current enable the heating element 3 to operate in an over-rated power state, the temperature of the heating element 3 rises rapidly to generate heat, and when the temperature reaches the surface liquid atomization value temperature, liquid in the liquid storage film 4 is converted into vapor fog. During the continuous conversion process, the lost liquid is replenished by the liquid storage body 5 through siphonage.
After the liquid in the liquid storage body is used, the heating body is destroyed.
When the cigarette is actually used, the heating body 3 can be a metal film resistor, the surface of the heating body is coated with a paint coat, a liquid storage film 4 (a high-temperature non-woven fabric sleeve) is sleeved, when the cigarette is selected to run by electric power which is several times to dozens of times higher than the rated power, the heating of the resistor can reach hundreds of degrees centigrade, because the surface of the metal film resistor is covered with the high-temperature non-woven fabric, when smoke liquid in the liquid storage cavity enters the high-temperature non-woven fabric through a siphon, the heat atomization of the metal film resistor is absorbed, the heat born by the metal film resistor is the heat capable of being born by the rated power, the rest heat is removed along with the atomization of the liquid, when the liquid is consumed and exhausted, the metal film resistor is burnt out, and the atomizer does not work any more.
A special case of the present invention: the electronic component selects a 20 ohm metal film resistor with rated power of 1/16W, the power supply voltage is 5V, when the electronic component works, the actual power added to the two ends of the metal film resistor is 1.2W, the generated heat can enable the surface temperature of the metal film resistor to reach 130 ℃, the heat generated by the energy of 15/16W is absorbed in the atomization process of the tobacco juice, when the tobacco juice (liquid medicine) is continuously supplied, the metal film resistor can continuously work, and the temperature reaches dynamic balance.
